Best Value Streaming Device For Stremio?

I want to be able to stream any link regardless of size (I use Torrentio+RD). Even if the link is a 4k 100+ GB REMUX file, I want it to be able to stream it perfectly without any buffering.

I also don't want to overspend because Stremio will most likely be the only app I use. Besides Youtube and like 2 other apps maybe.

I will be purchasing the streaming device that yall recommend the most.

Appreciate yall!

Edit - I purchased the $20 Onn 4k Streaming Box. I've never owned a streaming device so I just wanted to try this cheap one out and see the pros & cons. If I don't like it, I'll return it and invest in a more premium device.
